Comment 12 for bug 397696

Hi Giacomo, Mark,
I too have noticed that I am getting no more errors since my last update and
am also running kernel version 2.6.28-15, but on AMD64 -

Linux coffee 2.6.28-15-generic #52-Ubuntu SMP Wed Sep 9 10:48:52 UTC 2009 *
x86_64* GNU/Linux
mark@coffee:~$ cat /etc/modprobe.d/dvb-t.conf .
# Enable DiB0700 Low Noise Amps
options dvb-usb-dib0700 force_lna_activation=1
# Disable DVB remote(s)
options dvb-usb disable_rc_polling=1

Regards,
Mark O
